A 96% structural match of an auto-designed GA structure vs a professional reference, from a 42-page spec alone — 662 GA, 0 validation errors, HA package. No client data/files; reference used only as an anonymous benchmark. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

Case study — from a spec PDF to a validated 662-GA KNX structure, in minutes
🇷🇺 Русская версия: case-study.ru.md
The question
How far can a project specification alone be turned into a finished, standards-correct KNX group-address structure — and how close would it get to professional work?
Input
A real residential project — 14 rooms (~155 m²), Zennio-based: switched + dimmed lighting, electric underfloor heating, ventilation with heat recovery, motorised curtains, water / electricity / heat metering, leak & fire safety — described only in a 42-page technical specification (PDF). No group addresses, no DPTs, no naming were given: the spec lists equipment and functions, not a KNX structure.
The workflow
spec PDF
│ an AI assistant, grounded in the KNX Association standard + industry practice,
▼ DESIGNS the full group-address structure
GA structure (taxonomy · naming · DPTs · command/status pairs · scenes · reserves)
│ nickol-knx-mcp VALIDATES it and GENERATES the outputs
▼
Home Assistant package + ETS-importable group-address XML
Output
- 662 group addresses across 10 functional domains, as a
ga-export/01XML ready for ETS Import Group Addresses → place devices → export.knxproj. - Produced in minutes.
The check — against a professional reference implementation of the same project
| Metric | Result |
|---|---|
| Structural match | 96 % (662 vs 687 GA) |
| Domain taxonomy | 10 / 10 identical |
| Address names | 118 byte-identical, 68 % with a close analog |
| DPT discipline | exact sub-types throughout; DPT 5.001 ≈ 1 : 1 |
| Validation (nickol-knx-mcp) | 0 errors; reserve / logic noise auto-classified |
| Home Assistant | 9 climate zones · 11 shutters · 12 dimmers + sensors, generated directly |
What it shows
The standardised, time-consuming "skeleton" of a KNX project — the part defined by the standard and the equipment — can be auto-designed to near-professional quality in minutes, vs the days of manual group-address work. That frees the engineer's time for the genuinely creative part: the project-specific logic, which stays the engineer's craft (the residual few % are exactly those one-off logic functions).
Honesty notes
- No client data or project files are shared. The reference implementation is used only as an anonymous benchmark; the case study reports parameters and match figures, nothing identifying.
- The design is produced by an AI assistant grounded in KNX knowledge (the KNX Association standard + broad industry practice). nickol-knx-mcp's role is read-only validation and Home Assistant / ETS export — it never connects to a live bus.
- Figures are from a structure that actually passed the tool's own checks (0 errors).
